All well and good Tom but the problem of homelessness can’t be cured by Twitter & Uber. It needs a massive public housing project with Federal dollars, a jobs/universal income bill, and a whole new approach to addiction & mental health to reverse nearly 40 years of ignoring it. Sadly there is no way this is coming because the red states don’t care — especially as most of their most visible extremely poor and homeless are black. If Obama couldn’t get a public housing & works program through in 2009,how can we expect one now. Despite its wealth (and even if SF ended give away stop Uber, Twitter et al) San Francisco can not afford this on its own
